Drill bit Proline SDS+ 8 x 350 mm for rotary hammers — masonry drilling

Drill bit for industrial and professional use, designed for drilling in concrete, granite and other natural stones. The specially shaped carbide tip increases tool life, delivers high drilling efficiency and maintains centric drilling accuracy while reducing load. A double flute design provides fast dust removal. Compatible with rotary hammers that use an SDS+ shank. Size: 8 x 350 mm.

Advantages

The Proline SDS+ 8 x 350 mm drill bit features a reinforced carbide insert for extended durability and consistent cutting performance. Its double-spiral flute accelerates debris evacuation to maintain drilling speed and reduce clogging. The geometry of the tip improves centric accuracy, lowering the risk of bit walking and uneven holes. The SDS+ shank ensures secure connection to compatible rotary hammers.

Suitable for (tasks / use cases)

• Drilling holes in reinforced and non-reinforced concrete
• Boring into granite and other natural stone
• Masonry work in construction and renovation
• Professional and industrial drilling applications requiring SDS+ tools

How to use

Install the bit into a compatible rotary hammer with an SDS+ chuck, ensuring the shank locks securely. Select the hammer drilling mode and apply steady, even pressure without forcing the bit. Allow the tool and carbide tip to do the work; withdraw the bit periodically to clear debris and prevent overheating. For deeper holes, remove dust from the hole regularly to maintain drilling efficiency.

Usage recommendations

Use appropriate personal protective equipment such as safety goggles, hearing protection and dust mask. Match the drill speed and hammer power to the material being drilled; reduce feed pressure when encountering reinforcement or very hard stone. Store the bit dry and protected from impacts to preserve the carbide tip.
